The NW-20000-CNG from NoiseWave is a Noise Generator that operates from 18 to 22 GHz for satellite applications. This noise generator improves the speed and accuracy of BER (bit error rate) testing by automatically setting precise, stable, SNR (signal-to-noise), CNR (carrier-to-noise), and Eb/No (Bit energy to Noise Power Spectral Density) ratios for a user-supplied signal. It provides -55 to 5 dBm of noise power with a resolution of 0.1 dB and has an attenuation range of 60 dB in 0.1 dB steps. Using NoiseWave’s true AWGN noise modules, it achieves a minimum noise crest factor of 18 dB, allowing the user to test very low bit error rates.
The NW-20000-CNG has a gain of +/- 1 dB with a resolution of 0.1 dB and has a signal tracking range of +/- 4 dB. It has a C/N ratio accuracy of +/- 0.2 dB. The 75 ohms device features an optional AGC (automatic gain control). It can be mounted on a rack and measures 17 x 5.25 x 20 inches with a type-N (F) connector. This device can be controlled manually for engineering and laboratory testing or remotely via GPIB or Ethernet for automated production testing.
